Dorothy Gale and her dog Toto are swept away by a tornado from their home in Kansas to the magical land of Oz. They set off on a quest down a yellow brick road to see the Wizard, who can help them return home. Along the way, they are joined by others seeking the Wizard's help: a scarecrow, who wamts a brain; a Tin Man, who wants a heart; and a lion, who wants courage.
